177 unexpected test failures on a new system -- is this yet another linker issue?

[Ömer Sinan Ağacan]

I'm trying to validate on a new system (not sure if related, but it has gcc
6.2.1 and ld 2.27.0), and I'm having 177 unexpected failures, most (maybe
even
all) of them are similar to this one:

    =====> T5976(ext-interp) 1 of 1 [0, 0, 0]
    cd "./th/T5976.run" &&  "/home/omer/haskell/ghc/inplace/test
spaces/ghc-stage2" -c T5976.hs -dcore-dno-debug-output -XTemplateHaskell
-package template-haskell -fexternal-interpreter -v0
    Actual stderr output differs from expected:
    --- ./th/T5976.run/T5976.stderr.normalised      2016-11-10

Does anyone know what is this about?
